Some other faces are…
>:3c is a mischievous cat :3c is a soon to be mischievous cat. :3 is just a cat face or “kawaii face” as used by some people. owo is another cat face. >:) is also a mischievous or devilish face. >:D same as this one. ouo is a smiley face I believe.

I’ve always seen “.3.” as a face with the lips sorta in a ‘kissy’ shape, but instead of wanting to kiss it’s more like a “derp” face. The “-3-” face is basically the same thing but the eyes are closed in disappointment as if someone’s going “are you serious?” You can see this exact face used in anime.

originally it was like leting someone know you were completely bored and annoyed and were about to start devouring something (the other persons conversation) if things didn’t pick up and become more interesting quickly.

It can also be used as “oh” or “you don’t say” or other things like that.
It’s just a blank stare turned upside-down so it can be used in lots of situations.
The other version is ._. which isn’t turned upside-down.

Sorry, always forgetting to add the meaning. Typically it’s like when you on the phone or in person and your bf does something that gets you excited in a certain specific way and you become, pardon the pun, titillated!

This may be correct in that it is supposed to be a cat face, but it is not ‘awkward’ that is being shown by this face. It is more of a mischievous face. (e.g. come into the truck if you want the candy :3)

There are other faces where capitalization matters a lot as well. “:l” (which varies slightly in look depending on the font its typed in) is mainly a blank face while “:L” is a drooling face. “XD” and “xD” are the same face but on one, the eyes are smaller. Meanwhile “Xd” would be considered a typo and “xd” is a version of “XD” made to mock people who use the original (many think of it as an immature or overused face… and I partially agree but that’s just my personal opinion). Other people will say “ecks dee” or “Ecks DEEE” with a varying amount of E’s.

Most of these answers can be figured out on your own by simply imagining it as a face on a cartoon character. For some of them you will have to tilt the face sideways and for some you won’t. Just like in real life, faces can have multiple meanings depending on the situation, so look at context clues and try and match them up with the face that you’ve imagined. The different meanings of one face are usually similar though, and if you’re completely clueless just apologize and ask the person who sent the face.

;-; is a sad face that leans towards neutrality
o.o is suprise/shock
o.e / e.o is like twitching an eye almost as in saying “come on man” / a disappointment in disbelief in someone’s ignorance or the like
